  • This study was carried out to investigate the management and support system affecting to the occupational health nursing services(OHNS) provided in group occupational health agencies(GOHA). Questionnaire was developed and distributed to 82 nurses who were working in GOHA and who agreed to participate in the survey. The results were as follow: 1. OH nurses responded were mostly in the age of twenty to thirties(89%), married(73.7%), technical college graduates(88.9%), worked in hospital(85.4%) and participated more than 1 year in group occupational health services (96.3%). 2. Fifty eight point four percent of the OH nurses worked in number of workplace more than 30 to less than 60 in the OHNS form. The figure of workplaces undertaken by nurses was ranged greatly from 9 to more than 100. Number of employees who cared by nurses were mostly under 5,000 peoples in 93.3%. The types of industry was mostly manufacturing and located in the order of factory complex area, suburban, urban and others. 3. Most OH nurses(87.8%) were fully involved in the OHNS for the SSE. Their working days to visit SSE was 5 days per week(77.8%) and one day in the GOHA at 41.3%. 4. The OH documents using by nurses were found in more than 23 different types. However, they were largely summarized in the types of 'Workplace Health Management Card', 'Personal Health Counselling Card', 'Daily Health Management Report', 'Visiting List of Workplace' and 'Sick Employee List'. 5. The items of laboratory test provided by GOHA were mostly achieved in the purpose of basic health examination. They were used to be the blood pressure check(98.8%), blood sugar test (98.8%), urine sugar and protein(91.4%), SGOT and SGPT(85.3% each), cholesterol (82.9%), hepa vaccine immunization(82.9%), r-GPT(81.7%), hemoglobin(79.3%) and triglyceride(75.5%). 6. The OH nurses(92.7%) followed the work pattern to visit the GOHA before and after small-scale enterprises(SSE) visit by car driven by nurses in 74.3%. They were payed by GOHA for transportation fees in certain amounts. However, nurse is the main person(75.0%) who covers up in case of traffic accident. If the GOHA has no transportation regulation for the formal workplace visit, data showed that nurses had been responsible to take charge(31.7%). 7. The personnel manager who takes in charge for nursing services was 'nurse' in 61.7% and 41.2% worked as the final decision maker related to nursing work. The OH nurses' opinions about factors affecting to the management were classified in the four areas such as 'Nature(Quality) of health professional'. 'Content of OHNS', 'Delivery system of the GOHS', and 'Others'. The factors were indicated highly in 'Authority as health professional', 'Level of perception of director on the OH' and 'Physical work condition for OHNS'. The things that this study suggests in the recommendation would be summarized in such as the management and supporting system working for SSE in the OHNS is necessary to reform thoroughly. The reconsidered aspects might be in the matters of number of workplaces undertaken by nurses, development of effectively practical health documents, preparation for guideline of the laboratory test in the workpleces, establishment of convenient and encouraging support system and cooperation between other health professionals with respect and skill.

  • 창조경제시대의 실현을 위해 정부가 벤처창업 생태계 조성에 힘쓰고 있는 가운데 교육부는 국내 대학 내 창업교육의 확산을 위해 많은 노력과 지원을 아끼지 않고 있다. 창업교육은 개인에게 창업의 동기를 부여하고 시장의 혁신을 만들어 국가경제의 효율성 증대를 통한 성장으로 이어지기 때문에 창조경제의 실현을 위한 창업교육의 중요성도 날로 더해지고 있다. 이러한 중요성을 바탕으로 창업교육은 전국의 대학에 급속도로 확산되고 있다. 하지만, 확산되고 있는 창업교육에 비해 대학생들의 창업의지는 아직 크게 향상되지 못하고 있는 실정이다. 동일한 교육을 받은 학생이라 할지라도 학생들이 가지고 있는 환경이나 동기와 같은 특성에 따라 교육의 효과가 달라지기 때문에 이러한 요인들의 연구를 통해 좀 더 체계적인 창업교육의 방향을 도출할 필요가 있다. 대학 내 창업교육의 확산 분위기와 더불어 창업교육에 대한 국내의 연구도 점점 많아지고 있으며 특히 창업교육의 효과를 높이기 위해 어떻게 학생들의 창업의지를 높일 수 있을지에 대한 연구들이 많이 이루어지고 있다. 하지만 기존의 연구들은 학생들의 창업교육에 대한 만족이나 개인적인 환경이 어떻게 창업의지와 관계가 있는지에 대한 연구가 주를 이루었다. 본 연구에서는 직업의 한 부분으로써 창업을 이해하고 학생들의 직업선택 동기와 창업의지와의 관계를 살펴보았다. 본 연구를 위해 2012년 서울 및 경기지역에 창업교과목을 운영하고 있는 7개 대학의 학생들을 표본으로 선정하여 설문을 실시하였고 총 918부의 설문지를 회수하여 858부의 설문지를 분석하였다. 분석결과 학생들이 가지고 있는 직업선택의 동기의 요인에 따라 창업에 대한 자아효능감과 창업의지의 변수에 영향을 주는 관계가 규명되었다. 학생들의 자아실현과 혁신성 그리고 롤모델 추구의 직업선택의 동기 요인들은 창업에 대한 자아효능감에 긍정적인 영향을 주어 창업의지가 높아지는 결과가 나타났으며, 일반적인 관념과는 다르게 재무성취와 독립성을 추구하는 학생들은 창업의지와 유의한 상관관계를 보이지 않는 결과가 나타났다. 이러한 결과를 바탕으로 현재 대학 내 확산되고 있는 창업교육을 통해 창업의지를 향상시킬 수 있는 의미 있는 시사점을 도출하였고 이러한 연구결과는 정부가 추진하고 있는 창조경제 실현의 한 부분에 기여할 수 있을 것으로 기대된다.

  • 20世纪60年代中期, 随着1967年 ${\ll}$产业购买和创造营销${\gg}$的出版, 组织购买行为这一领域的兴起为企业如何在市场中运作提供了新的思维方式, 而不只是为最终用户服务. 无论是 "工业营销" 或 "企业营销"(B-to-B),组织的购买行为仍然是这个领域的核心. 本文探讨了动态因素的影响,影响了几个组织彼此相关的迅速增长的相互依存,反过来会影响组织的购买行为. 文章还提出了一个问题,组织购买行为的概念模型,在一个相互依存的世界是否仍然会在这个充满活力的经营环境中引导研究和管理的思想,. 本文提出并探索三个关于组织相互依存的问题: 1.哪些因素和趋势驱动了组织的相互依存的兴起? 2.在过去半个世纪中发展起来的组织购买行为的主要概念模型仍然适用于今天这个相互依存的组织的世界吗? 3.研究中组织的相互依存的启示是什么? 组织购买行为的实践活动是什么? 考虑到组织关系中驱动组织的相互依存的因素和趋势和5个关键驱动因素有关并影响他们的购买行为:加速全球化, 平整的网络组织, 破坏价值链, 强化政府的介入, 不断细分客户需求. 这五个相通的相互依存和潜在的技术上的优势可以改变组织购买产品和服务的市场中保持竞争力的关系. 在一个客户驱动的营销策略背景下, 这些力量影响三个层次的战略发展: (1)进化的客户需求, (2)产生的产品/服务和解决方案以满足这些需求, 和(3)的组织能力和工艺制定和实施了以满足需求. 组织中相互依存的五个驱动因素在他们影响组织如何购买时不需要独立的操作. 他们可以相互作用和更加有效的影响组织购买行为. 例如,加速了全球化的影响,出现了新的网络进一步破坏传统价值链之间的关系, 从而改变机构购买的产品和服务. 提高政府参与可能会增加成本,因此在其它国家的新兴市场开公司做生意寻求低成本的来源. 这可以减少一国的就业机会增加另一个国家的就业机会, 在另一方面, 从而进一步加速全球化. 第二个主要的问题是相互依存的五个驱动因素对组织购买行为的核心概念模型有什么影响. 考虑三个在 ${\ll}$产业购买和创造营销${\gg}$${\ll}$组织购买行为${\gg}$ 书籍中发展的概念模型:组织购买过程, 购买中心,以及购买的情况. 回顾这些核心模型, 作为最初的概念,他们仍然是有效的, 而且不可能改变. 在买家和卖家相互依赖的情况下, 什么会改变买卖双方相互作用的方式. 例如,增加了相互依赖的机会可能导致增加协作以及组织之间的冲突的买卖,从而改变购买过程. 此外,组织中的沟通过程的重要性作为一个成功的购买关系的判断依据将增加. 第三个问题对这些组织购买行为的关系的影响和意义进行了探讨. 以下是本文所考虑到的: 为了增进对网络对组织购买行为的影响的理解,需要增加了解所扮演的角色之间的信任, 增强在网络环境中如何管理组织购买的理解的需要, 需要增加了解在价值网络中的客户需要,并且需要增加了解新兴的商业模式对组织购买行为的影响. 在许多方面,这些从增加的组织的相互依存派生出来的需要是组织购买行为传统概念的扩展. 在1977年,Nicosia 和Wind建议把焦点集中在组织间而不是组织内部观点,自1990年以来, 这个趋势的势头很强. 对于管理者来说,也想在越来越相互依存的世界中生存,他们将需要更好地了解组织如何与另一组织相关的复杂性. 从组织的相互依存的观点已经开始,必须不断地发展提出一种对这些重要的关系改进的理解. 互相依赖的网络观点的转变需要很多学术界人士和实践者从根本上挑战和改变他们商业中的心智模型和组织购买行为模型. 不再只关注购买组织和销售组织之间的关系而应该是网络中所有的相关成员, 包括消费者, 发展者, 供应商和中间者. 我们来看这个例子. 由SAP创造的有众多合作伙伴的网络包含了超过9000个公司和超过一百万的参与者. 互相依赖的进展, 复杂性和不确定的现实和多变的网络需要重新考虑如何做出购买决定. 结果是他们应该关注学术中下一阶段的研究和理论建设并关注有实践者构建的实践模型和实验. 我们希望这样的研究能够展开, 不是孤立在象牙塔里, 也不是限制在商业世界中, 而是学术和实践的结合. 总而言之, 组织之间相互依赖的提高的考虑揭示了组织购买行为的基础模型的持续关联性. 然而在相互依存的世界中来提高这些模型的价值, 学术界和实践者应该提高他们对一下内容的理解 (1)网络的影响; (2)如何更好地管理这些影响的作用; (3)组织之间信任和价值的作用, (4)价值网络中客户需求的演变; (5)组织购买行为的新兴的新商业模型的影响. 为了实现这一目标, 我们需要产业界和学习界更好的合作从而提高我们对在相互依赖的世界中的组织购买行为的理解.

  • This project was a service-cum-research effort with a quasi-experimental study design to examine the health benefits of an integrated Family Planning (FP)/Maternal & Child health (MCH) Service approach that provides crucial factors missing in the present on-going programs. The specific objectives were: 1) To test the effectiveness of trained nurse/midwives (MW) assigned as change agents in the Health Sub-Center (HSC) to bring about the changes in the eight FP/MCH indicators, namely; (i)FP/MCH contacts between field workers and their clients (ii) the use of effective FP methods, (iii) the inter-birth interval and/or open interval, (iv) prenatal care by medically qualified personnel, (v) medically supervised deliveries, (vi) the rate of induced abortion, (vii) maternal and infant morbidity, and (viii) preinatal & infant mortality. 2) To measure the integrative linkage (contacts) between MW & HSC workers and between HSC and clients. 3) To examine the organizational or administrative factors influencing integrative linkage between health workers. Study design; The above objectives called for quasi-experimental design setting up a study and control area with and without a midwife. An active intervention program (FP/MCH minimum 'package' program) was conducted for a 2 year period from June 1982-July 1984 in Seosan County and 'before and after' surveys were conducted to measure the change. Service input; This study was undertaken by the Soonchunhyang University in collaboration with WHO. After a baseline survery in 1981, trained nurses/midwives were introduced into two health sub-centers in a rural setting (Seosan county) for a 2 year period from 1982 to 1984. A major service input was the establishment of midwifery services in the existing health delivery system with emphasis on nurse/midwife's role as the link between health workers (nurse aids) and village health workers, and the referral of risk patients to the private physician (OBGY specialist). An evaluation survey was made in August 1984 to assess the effectiveness of this alternative integrated approach in the study areas in comparison with the control area which had normal government services. Method of evaluation; a. In this study, the primary objective was first to examine to what extent the FP/MCH package program brought about changes in the pre-determined eight indicators (outcome and impact measures) and the following relationship was first analyzed; b. Nevertheless, this project did not automatically accept the assumption that if two or more activities were integrated, the results would automatically be better than a non-integrated or categorical program. There is a need to assess the 'integration process' itself within the package program. The process of integration was measured in terms of interactive linkages, or the quantity & quality of contacts between workers & clients and among workers. Intergrative linkages were hypothesized to be influenced by organizational factors at the HSC clinic level including HSC goals, sltrurture, authority, leadership style, resources, and personal characteristics of HSC staff. The extent or degree of integration, as measured by the intensity of integrative linkages, was in turn presumed to influence programme performance. Thus as indicated diagrammatically below, organizational factors constituted the independent variables, integration as the intervening variable and programme performance with respect to family planning and health services as the dependent variable: Concerning organizational factors, however, due to the limited number of HSCs (2 in the study area and 3 in the control area), they were studied by participatory observation of an anthropologist who was independent of the project. In this observation, we examined whether the assumed integration process actually occurred or not. If not, what were the constraints in producing an effective integration process. Summary of Findings; A) Program effects and impact 1. Effects on FP use: During this 2 year action period, FP acceptance increased from 58% in 1981 to 78% in 1984 in both the study and control areas. This increase in both areas was mainly due to the new family planning campaign driven by the Government for the same study period. Therefore, there was no increment of FP acceptance rate due to additional input of MW to the on-going FP program. But in the study area, quality aspects of FP were somewhat improved, having a better continuation rate of IUDs & pills and more use of effective Contraceptive methods in comparison with the control area. 2. Effects of use of MCH services: Between the study and control areas, however, there was a significant difference in maternal and child health care. For example, the coverage of prenatal care was increased from 53% for 1981 birth cohort to 75% for 1984 birth cohort in the study area. In the control area, the same increased from 41% (1981) to 65% (1984). It is noteworthy that almost two thirds of the recent birth cohort received prenatal care even in the control area, indicating that there is a growing demand of MCH care as the size of family norm becomes smaller 3. There has been a substantive increase in delivery care by medical professions in the study area, with an annual increase rate of 10% due to midwives input in the study areas. The project had about two times greater effect on postnatal care (68% vs. 33%) at delivery care(45.2% vs. 26.1%). 4. The study area had better reproductive efficiency (wanted pregancies with FP practice & healthy live births survived by one year old) than the control area, especially among women under 30 (14.1% vs. 9.6%). The proportion of women who preferred the 1st trimester for their first prenatal care rose significantly in the study area as compared to the control area (24% vs 13%). B) Effects on Interactive Linkage 1. This project made a contribution in making several useful steps in the direction of service integration, namely; i) The health workers have become familiar with procedures on how to work together with each other (especially with a midwife) in carrying out their work in FP/MCH and, ii) The health workers have gotten a feeling of the usefulness of family health records (statistical integration) in identifying targets in their own work and their usefulness in caring for family health. 2. On the other hand, because of a lack of required organizational factors, complete linkage was not obtained as the project intended. i) In regards to the government health worker's activities in terms of home visiting there was not much difference between the study & control areas though the MW did more home visiting than Government health workers. ii) In assessing the service performance of MW & health workers, the midwives balanced their workload between 40% FP, 40% MCH & 20% other activities (mainly immunization). However, $85{\sim}90%$ of the services provided by the health workers were other than FP/MCH, mainly for immunizations such as the encephalitis campaign. In the control area, a similar pattern was observed. Over 75% of their service was other than FP/MCH. Therefore, the pattern shows the health workers are a long way from becoming multipurpose workers even though the government is pushing in this direction. 3. Villagers were much more likely to visit the health sub-center clinic in the study area than in the control area (58% vs.31%) and for more combined care (45% vs.23%). C) Organization factors (admistrative integrative issues) 1. When MW (new workers with higher qualification) were introduced to HSC, it was noted that there were conflicts between the existing HSC workers (Nurse aids with less qualification than MW) and the MW for the beginning period of the project. The cause of the conflict was studied by an anthropologist and it was pointed out that these functional integration problems stemmed from the structural inadequacies of the health subcenter organization as indicated below; i) There is still no general consensus about the objectives and goals of the project between the project staff and the existing health workers. ii) There is no formal linkage between the responsibility of each member's job in the health sub-center. iii) There is still little chance for midwives to play a catalytic role or to establish communicative networks between workers in order to link various knowledge and skills to provide better FP/MCH services in the health sub-center. 2. Based on the above findings the project recommended to the County Chief (who has power to control the administrative staff and the technical staff in his county) the following ; i) In order to solve the conflicts between the individual roles and functions in performing health care activities, there must be goals agreed upon by both. ii) The health sub·center must function as an autonomous organization to undertake the integration health project. In order to do that, it is necessary to support administrative considerations, and to establish a communication system for supervision and to control of the health sub-centers. iii) The administrative organization, tentatively, must be organized to bind the health worker's midwive's and director's jobs by an organic relationship in order to achieve the integrative system under the leadership of health sub-center director. After submitting this observation report, there has been better understanding from frequent meetings & communication between HW/MW in FP/MCH work as the program developed. Lessons learned from the Seosan Project (on issues of FP/MCH integration in Korea); 1) A majority or about 80% of the couples are now practicing FP. As indicated by the study, there is a growing demand from clients for the health system to provide more MCH services than FP in order to maintain the achieved small size of family through FP practice. It is fortunate to see that the government is now formulating a MCH policy for the year 2,000 and revising MCH laws and regulations to emphasize more MCH care for achieving a small size family through family planning practice. 2) Goal consensus in FP/MCH shouBd be made among the health workers It administrators, especially to emphasize the need of care of 'wanted' child. But there is a long way to go to realize the 'real' integration of FP into MCH in Korea, unless there is a structural integration FP/MCH because a categorical FP is still first priority to reduce the rate of population growth for economic reasons but not yet for health/welfare reasons in practice. 3) There should be more financial allocation: (i) a midwife should be made available to help to promote the MCH program and coordinate services, (in) there should be a health sub·center director who can provide leadership training for managing the integrated program. There is a need for 'organizational support', if the decision of integration is made to obtain benefit from both FP & MCH. In other words, costs should be paid equally to both FP/MCH. The integration slogan itself, without the commitment of paying such costs, is powerless to advocate it. 4) Need of management training for middle level health personnel is more acute as the Government has already constructed 90 MCH centers attached to the County Health Center but without adequate manpower, facilities, and guidelines for integrating the work of both FP and MCH. 5) The local government still considers these MCH centers only as delivery centers to take care only of those visiting maternity cases. The MCH center should be a center for the managment of all pregnancies occurring in the community and the promotion of FP with a systematic and effective linkage of resources available in the county such as i.e. Village Health Worker, Community Health Practitioner, Health Sub-center Physicians & Health workers, Doctors and Midwives in MCH center, OBGY Specialists in clinics & hospitals as practiced by the Seosan project at primary health care level.

  • 기업신용등급은 금융시장의 신뢰를 구축하고 거래를 활성화하는데 있어 매우 중요한 요소로서, 오래 전부터 학계에서는 보다 정확한 기업신용등급 예측을 가능케 하는 다양한 모형들을 연구해 왔다. 구체적으로 다중판별분석(Multiple Discriminant Analysis, MDA)이나 다항 로지스틱 회귀분석(multinomial logistic regression analysis, MLOGIT)과 같은 통계기법을 비롯해, 인공신경망(Artificial Neural Networks, ANN), 사례기반추론(Case-based Reasoning, CBR), 그리고 다분류 문제해결을 위해 확장된 다분류 Support Vector Machines(Multiclass SVM)에 이르기까지 다양한 기법들이 학자들에 의해 적용되었는데, 최근의 연구결과들에 따르면 이 중에서도 다분류 SVM이 가장 우수한 예측성과를 보이고 있는 것으로 보고되고 있다. 본 연구에서는 이러한 다분류 SVM의 성능을 한 단계 더 개선하기 위한 대안으로 유전자 알고리즘(GA, Genetic Algorithm)을 활용한 최적화 모형을 제안한다. 구체적으로 본 연구의 제안모형은 유전자 알고리즘을 활용해 다분류 SVM에 적용되어야 할 최적의 커널 함수 파라미터값들과 최적의 입력변수 집합(feature subset)을 탐색하도록 설계되었다. 실제 데이터셋을 활용해 제안모형을 적용해 본 결과, MDA나 MLOGIT, CBR, ANN과 같은 기존 인공지능/데이터마이닝 기법들은 물론 지금까지 가장 우수한 예측성과를 보이는 것으로 알려져 있던 전통적인 다분류 SVM 보다도 제안모형이 더 우수한 예측성과를 보임을 확인할 수 있었다.

  • 신규 제초제 작용점의 발굴은 유전체학과 조합화학 등 새로운 기술이 등장하여 그 가능성이 높아지고 있다. 대략 $10^{30}$에서 $10^{50}$여 개의 화학물질의 합성이 가능하고 50,000여 개의 식물 유전자 지도가 완성되어 이들의 조합으로 새로운 제초제의 작용점 발굴 가능성이 높아지게 될 것이다. 즉, 고등식물이 가지고 있는 50,000여 개의 유전자 가운데 0.1%, 1.0% 또는 10%가 신규 작용점이 된다면 50, 500, 5000개의 신규 작용점을 발견할 수 있는 것이다. 신규 제초제의 개발을 위해서는 target enzyme의 선택과 결정, 저해제의 설계, 작용점까지 도달하는 과정, 대사적인 운명 등 여러가지 요인들이 검토되어야 한다. 이러한 과정에서 가장 중요한 것은 확실한 작용점의 선택에 있다. 또한 다양한 생화학적 정보를 통하여 작용점/효소의 저해로부터 고사에 이르는 과정을 이해함은 물론 보다 강력한 저해제의 합성과 살초과정을 이해할 수 있어야 할 것이다. 그 동안에는 이미 알려진 작용점을 대상으로 신규 화합물을 합성하거나 유도체를 개발하는 것이 대부분이었지만 최근에는 antisense 기법 등을 활용하여 새로운 치사관련 작용점을 찾아내는데 잠재력과 가능성을 확대시켜주고 있다. 새로운 치사관련 작용점을 발굴한 후에는 대상효소의 화학적, 생화학적 기능과 단백질의 구조를 분석하여 강력한 저해제를 설계하는데 활용하게 될 것이다. 치사관련 돌연변이체와 antisense 기법을 활용하고, 식물 생리학적 반응을 기초로 하여 리드화합물을 탐색하는 것은 새로운 접근방식이며 농약 화학적 특성을 갖는 효소 저해제들의 합성은 크게 6가지로 할 수 있다. 공통특이시얀 기질 유사체 합성, affinity labels, 자살기질체, 반응중간산물, 그리고 extraneous site inhibitors 등을 들 수 있다. 이와 같은 방법으로 후보화합물이 선발된다 하여도 실제식물에 처리하여 흡수, 이행, 대사 등에 관한 시험이 반드시 이루어져야 새로운 제초제를 탄생시킬 수 있다. 또한 약물의 전달과정과 무독화작용을 통하여 pro-herbicide에 대한 연구를 진행하게 될 것이며, 마지막으로 잡초와 작물간의 선택성이 고려되어야 효소 측이적 접근방식에 의한 신규 선택성 제초제의 개발이 성공할 수 있는 것이다.

  • G20 정상회의 시 발생 가능한 위협요인으로 요인테러, 인질테러, 폭탄테러, 다중이용시설 테러, 항공기테러 등 이 예상된다. 한국에서 예상되는 위협집단으로는 북한, 이슬람 과격집단 및 국제회의를 반대하는 NGO 조직 등의 단체가 위해를 일으킬 가능성이 있다고 본다. 이에 본 연구는 G20 정상회의가 주로 진행되는 장소인 주행사장과 숙소에서의 VIP 안전대책이 매우 중요하다고 판단하여 이에 대한 방안을 제시하는데 연구의 목적이 있다. 본 연구에서는 국내 최초로 경호원리 중 세계 각국에서 공통적으로 '3선경호원리'를 채택하고 있으므로 이 원리에 입각하여 1선(안전구역) 2선(경비구역) 3선(경계구역)별로 대응방안을 도출하고 VIP 안전대책을 위하여 정책적으로 반영하여야 할 의견도 함께 제시하였다. 결론적으로 G20 정상회의에 대비하여 주(主) 행사장에서의 VIP 안전대책을 위한 방안으로 1선(안전구역)에서는 첫째, 직가시 승하차지점에 대한 차단대책 강구해야 한다. 둘째, 노출지역에서는 과감하게 근접도보대형을 강화해야 한다. 2선(경비구역)에서는 첫째, 주 행사장의 특수성을 고려하여 출입통제대책을 강구해야 한다. 둘째, 행사비표 내에 RFID 기능이 포함된 효율적인 비표운용계획을 도입해야 한다. 3선(경계구역)에서는 첫째, 각종 요인테러대비, 정 첩보 수집 및 해외 정보기관과의 공조 하에 대테러 정보수집체계를 강화해야 한다. 둘째, 경호 행사인력에 대한 유사시 비상대책훈련을 실시해야 한다. 셋째, VIP 제대의 일정한 속도를 유지하기 위하여 효율적인 교통통제시스템을 운용해야 한다. 마지막으로 VIP 안전대책을 위해 정책적으로 반영하여야 할 점은 첫째, VIP 숙소의 효율적인 분산배치 및 통제가 이루어져야 한다. 둘째, 다양한 기만작전을 활용하여 불순분자가 오판하여 공격이 실패하도록 하여야 한다. 셋째, 북한 대남공작 기구의 개편에 따라 금번 G20 정상회의부터는 강력한 '군사지원대책'을 추진해야 한다. 이를 위해 국방부 주관 하에 전 후방 군사대비태세를 보다 강화하고, 화생방테러에 대비하여 탐지 및 제독에도 적극 적으로 대응할 것을 제안하고자 한다.

  • 본 논문에서는 미가공 말뭉치 데이터를 활용하여 영한 기계번역 시스템의 대역어 선택 시 발생하는 중의성을 해소하는 방법을 제안한다. 이를 위하여 은닉 의미 분석(Latent Semantic Analysis : LSA)과 확률적 은닉 의미 분석(Probabilistic LSA : PLSA)을 적용한다. 이 두 기법은 텍스트 문단과 같은 문맥 정보가 주어졌을 때, 이 문맥이 내포하고 있는 복잡한 의미 구조를 표현할 수 있다 본 논문에서는 이들을 사용하여 언어적인 의미 지식(Semantic Knowledge)을 구축하였으며 이 지식은 결국 영한 기계번역에서의 대역어 선택 시 발생하는 중의성을 해소하기 위하여 단어간 의미 유사도를 추정하는데 사용된다. 또한 대역어 선택을 위해서는 미리 사전에 저장된 문법 관계를 활용하여야 한다. 본 논문에서는 이러한 대역어 선택 시 발생하는 데이터 희소성 문제를 해소하기 위하여 k-최근점 학습 알고리즘을 사용한다. 그리고 위의 두 모델을 활용하여 k-최근점 학습에서 필요한 예제 간 거리를 추정하였다. 실험에서는, 두 기법에서의 은닉 의미 공간을 구성하기 위하여 TREC 데이터(AP news)론 활용하였고, 대역어 선택의 정확도를 평가하기 위하여 Wall Street Journal 말뭉치를 사용하였다. 그리고 은닉 의미 분석을 통하여 대역어 선택의 정확성이 디폴트 의미 선택과 비교하여 약 10% 향상되었으며 PLSA가 LSA보다 근소하게 더 좋은 성능을 보였다. 또한 은닉 공간에서의 축소된 벡터의 차원수와 k-최근점 학습에서의 k값이 대역어 선택의 정확도에 미치는 영향을 대역어 선택 정확도와의 상관관계를 계산함으로써 검증하였다.젝트의 성격에 맞도록 필요한 조정만을 통하여 품질보증 프로세스를 확립할 수 있다. 개발 된 패키지의 효율적인 활용이 내조직의 소프트웨어 품질보증 구축에 투입되는 공수 및 어려움을 줄일 것으로 기대된다.도가 증가할 때 구기자 열수 추출 농축액은 $1.6182{\sim}2.0543$, 혼합구기자 열수 추출 농축액은 $1.7057{\sim}2.1462{\times}10^7\;J/kg{\cdot}mol$로 증가하였다. 이와 같이 구기자 열수 추출 농축액과 혼합구기자 열수 추출 농축액의 리올리지적 특성에 큰 차이를 나타내지는 않았다. security simultaneously.% 첨가시 pH 5.0, 7.0 및 8.0에서 각각 대조구의 57, 413 및 315% 증진되었다. 거품의 열안정성은 15분 whipping시, pH 4.0(대조구, 30.2%) 및 5.0(대조구, 23.7%)에서 각각 $0{\sim}38.0$$0{\sim}57.0%$이었고 pH 7.0(대조구, 39.6%) 및 8.0(대조구, 43.6%)에서 각각 $0{\sim}59.4$$36.6{\sim}58.4%$이었으며 sodium alginate 첨가시가 가장 양호하였다. 전체적으로 보아 거품안정성이 높은 것은 열안정성도 높은 경향이며, 표면장력이 낮으면 거품형성능이 높아지고, 비점도가 높으면 거품안정성 및 열안정성이 높아지는 경향이 있었다.protocol.eractions between application agents that are developed using different

  • 대규모 면오염원으로 간주되는 난지도지역을 중심으로 2000년 봄 기간중 대기-지표간 수은의 교환율을 측정하고, 측정자료를 기초로 수은의 교환현상을 분석하였다. 측정결과에 의하면 난지도지역은 대규모 면오염원으로 대량의 수은을 배출할 뿐아니라 동시에 대규모의 침적을 경험하는 것으로 나타났다. 일주기별로 농도, 농도구배, 플럭스의 절대치를 분석한 결과 대규모 배출과 침적은 오후시간대에 왕성하게 진행되는 것으로 나타났다. 그러나 이들의 발생빈도에 대한 분석결과는 배출이 새벽 또는 저녁에 빈번하게 발생하는데 비해, 침적은 주로 오후시간대에 집중된다는 것을 확인하였다. 풍향대별로 발생빈도와 교환율을 비교한 바에 따르면, 대규모 침적을 유도하는 외부배출원이 동쪽지역에 위치해 있다는 것을 추정할 수 있었다. 특정 풍향에서 침적이 집중된 점을 감안하여, 침적이 집중된 방향의 자료군과 배출이 지배적으로 발견된 전체자료를 이용하여 조건별 환경인자의 변화동향을 배출/침적비로 환산하여 비교하였다. 그 결과 대부분의 오염인자들의 농도는 외부여건에 따라 규칙적인 변화양상을 보여주었다. 상관분석의 결과는 이들의 거동이 교환현상의 수직적인 방향-침적 또는 배출-의영향을 민감하게 반영하는 것으로 나타났다. 요인분석의 결과는 배출시에 기온과 같은 요인에 의해 유도되는 부분이 그리고 침적시에는 기온, 오존, 비메탄계 탄화수소와 같이 외부인자의 영향을 반영하는 요인들이 복합적으로 중요하게 작용할 수 있다는 점을 시사하였다. 난지도지역을 중심으로 한 수은의 자료를 추정한 결과 연간규모로 약 6kg의 수은이 배출되는 것으로 나타났다.

  • It seems high time to increase productivity by adopting e-business to overcome challenges posed by both external factors including the appreciation of Korean won, oil hikes and fierce global competition and domestic issues represented by disparities between large corporations and small and medium enterprises (SMEs), Seoul metropolitan and local cities, and export and domestic demand all of which weaken future growth engines in the Korean economy. The demands of the globalization era are for innovative changes in businessprocess and industrial structure aiming for creating new values. To this end, e-business is expected to play a core role in the sophistication of the Korean economy through new values and innovation. In order to examine business performance in e-business-adopting industries, this study analyzed the home shopping industry by closely looking into the financial ratios including the ratio of net profit to sales, the ratio of operation income to sales, the ratio of gross cost to sales cost, the ratio of gross cost to selling, general and administrative (SG&A) expense, and return of investment (ROI). This study, for best outcome, referred to corporate financial statements as a main resource to calculate financial ratios by utilizing Data Analysis, Retrieval and Transfer System (DART) of the Financial Supervisory Service, one of the Korea's financial supervisory authorities. First of all, the result of the trend analysis on the ratio of net profit to sales is as following. CJ Home Shopping has registered a remarkable increase in its ratio of net profit rate to sales since 2002 while its competitors find it hard to catch up with CJ's stunning performances. This is partly due to the efficient management compared to CJ's value of capital. Such significance, if the current trend continues, will make the front-runner assume the largest market share. On the other hand, GS Home Shopping, despite its best organized system and largest value of capital among others, lacks efficiency in management. Second of all, the result of the trend analysis on the ratio of operation income to sales is as following. Both CJ Home Shopping and GS Home Shopping have, until 2004, recorded similar growth trend. However, while CJ Home Shopping's operating income continued to increase in 2005, GS Home Shopping observed its operating income declining which resulted in the increasing income gap with CJ Home Shopping. While CJ Home Shopping with the largest market share in home shopping industryis engaged in aggressive marketing, GS Home Shopping due to its stability-driven management strategies falls behind CJ again in the ratio of operation income to sales in spite of its favorable management environment including its large capital. Companies in the Group B were established in the same year of 2001. NS Home Shopping was the first in the Group B to shift its loss to profit. Woori Home Shopping has continued to post operating loss for three consecutive years and finally was sold to Lotte Group in 2007, but since then, has registered a continuing increase in net income on sales. Third of all, the result of the trend analysis on the ratio of gross cost to sales cost is as following. Since home shopping falls into sales business, its cost of sales is much lower than that of other types of business such as manufacturing industry. Since 2002 in gross costs including cost of sales, SG&A expense, and non-operating expense, cost of sales turned out to have remarkably decreased. Group B has also posted a notable decline in the same sector since 2002. Fourth of all, the result of the trend analysis on the ratio of gross cost to SG&A expense is as following. Due to its unique characteristics, the home shopping industry usually posts ahigh ratio of SG&A expense. However, more than 80% of SG&A expense means the result of lax management and at the same time, a sharp lower net income on sales than other industries. Last but not least, the result of the trend analysis on ROI is as following. As for CJ Home Shopping, the curve of ROI looks similar to that of its investment on fixed assets. As it turned out, the company's ratio of fixed assets to operating income skyrocketed in 2004 and 2005. As far as GS Home Shopping is concerned, its fixed assets are not as much as that of CJ Home Shopping. Consequently, competition in the home shopping industry, at the moment, is among CJ, GS, Hyundai, NS and Woori Home Shoppings, and all of them need to more thoroughly manage their costs. In order for the late-comers of Group B and other home shopping companies to advance further, the current lax management should be reformed particularly on their SG&A expense sector. Provided that the total sales volume in the Internet shopping sector is projected to grow over 20 trillion won by the year 2010, it is concluded that all the participants in the home shopping industry should put strategies on efficient management on costs and expenses as their top priority rather than increase revenues, if they hope to grow even further after 2007.
